The Maryland Transportation Authority Police found out about the three-car accident just after 3 p.m.

MdTA police spokesman 1st Sgt. Jonathan Green said that a Toyota driven by a teenage girl was headed northbound when she struck a Ford truck headed southbound. The truck rolled over as a result of the collision. The Toyota proceeded to strike a Chevy truck also headed southbound.

The girl was transported to University of Maryland Charles Regional Medical Center in La Plata for injuries that were not life-threatening, police said.

Sadie Estevez, 29, the driver of the Ford truck, was treated on the scene for injuries that also were not life-threatening. Her passengers, Donny Newkirk, 27, and two children, were transported to the Charles Regional Medical Center with injuries that were not life-threatening.

The driver of the Chevy truck, Lionel Turner, 33, was not injured.

Green said a second accident occurred as a result of the original accident. He said that the driver of a car slowed to avoid hitting the cars in the first crash and was struck from behind by another car.

Green said that the Charles County Sheriff’s Office assisted with traffic on the Maryland side of the bridge.

The sheriff’s office activated its local traffic detour plan, which allows residents who live on the Cobb Neck and Route 257 corridor or in Cliffton on the Potomac to get to their homes when traffic is backed up for several miles, as was the case Monday.

The bridge was closed for about two hours and 45 minutes Monday as a result of the two accidents and a tractor-trailer that became disabled while in traffic.
